We purchased all sizes (first a test order, then a second order, 15 pouches in total).

Products are well made. The colors help with coding contents when traveling (e.g. orange contains medicine, white contains paper, etc.). I tested water resistance by placing a paper tissue inside a pouch, then dribbling water over the closed zipper slider to mimic my multiple experiences being caught unprepared in heavy rains. The tissue remained dry.

I then ran a small stream of water over the closed zipper slider. Again the tissue remained dry. Similar products by other purveyors did not pass even the dribble test. Items are value (well) priced and also priced below competing products.

I cannot comment on durability (I have only used for a very short time) but YYK zippers and woven Dyneema, based on my prior experience, suggest durability will not be an issue.

The pencil pouch is also very nice. Fulfillment was fast with good messaging (order received, order shipped, order out for delivery, order delivered). My wife and I are fans.

Great little sack, well built. My rain kilt fits perfectly in this size.

This bag is just what I was looking for. I ordered the large. Love the color. Very well made. Lightning fast shipping

Well made wallet. Sewing is pristine. Thanks!
